Comments for executive programs:
1)
Devices ‘S2000-SP1’ ver
1.20
and ‘S2000-4’ ver
1.07
support extended relay output
controlling, e.g, delayed controlling or control time being given in the range from 0 to 8191,875
seconds and 1/8 second resolution. In addition these devices support various types of blinking
differing by period and pulse ratio. If the equipment does not support extended output relay
control, it cannot allow delayed controlling, blinking can be realized with frequency 1 Hz and
pulse ratio 2 only, control time can be given in range from 0 to 255 seconds with 1 second
resolution.
2)
One can give the the delayed controlling for all programs except
№№
9, 10, 13, 14,
15, 16.
3)
Outputs with permanent executive programs (e.g, “On” or “Alarm output”) are turned
on (both for opening and closing) when meeting the appropriate conditions and retain in such
state until the condition avoids. After condition disapearing relay outputs return to initial state.
On the contrary to permanent executive programs outputs with time given programs (that is with
limited control time) return to initial state not only when disappearing conditions but if the time
has elapsed. Time given programs will operate identically with permanent programs if given
time has the maximum value being equal 8191,875 second.

Programs

11, 33, 34 and 35 are designed to control the fire automatic equipment
including autoextinguishing devices. According to the autoextinguishing systems requirements
one can activated the extinguishing equipment on premises when there is fire alarm in two
independent fire alarm loops checking this premises. To avoid the leak of extinguishing
compound (gas, powder) it is allowed to start the equipment only if all doors are opened. In
addition it is necessary to check the light and audible annunciators control circuits and block up
the fire extinguishing launching when such circuits troubles. The door state is controlled by
means of alarm loops known as
auxiliary
. If such loop is broken (i.e. the door is opened) it takes
the “Auxiliary loop alarm” status but if close door condition restored this loop automatically
restore its state after
auxiliary loop
recovery time
. To control light and audible annunciators one
can use “S2000-KPB” outputs being able to control short or open failures of load circuit. Output
executive programs are realized so that launching is blocked up if auxiliary loop or output circuit
is failed. As mentioned above to create automatic fire extinguishing controlling the premises is to
be controlled by at least two fire alarm loops, the doors are to be monitored via auxiliary alarm
loops and annunciators are to be controlled by means of “S2000-KPB”. This loops and outputs
form one fire partition associated with one or more outputs designated to give the launching
pulse and being controlled by “ASPT” program. It two or more fire loops in partition alarm the
relay output turns on with given time and delay provided all doors are closed and annunciators
are operative. If at least one door is opened or at least one annunciator circuit is failed the relay
does not start. If two latter conditions disappear with fire alarm being retain then outputs
